I think 1991 it was the fall of soviet union
Explanation:
At the center its weight is zero. Or you can argue by symmetry: if the weight is not zero, in what direction would it act?
Answer:
The answer it's on the Explanation:
Explanation:
The origins of the great civilization known as the Byzantine Empire can be traced to 330 A.D., when the Roman emperor Constantine the Great dedicated a "new Rome" on the site of the ancient Greek colony of Byzantium. Though the western half of the Roman Empire fell in 476, the eastern half survived for 1,000 more years, spawning a rich tradition of art, literature and learning and serving as a military buffer between the states of Europe and the threat of invasion from Asia. The Byzantine Empire finally fell in 1453, after an Ottoman army stormed the Byzantine Empire during the reign of Constantine XI.
Weather is a complex phenomena. in order to solve engineering problems such as the prediction of weather, we utilize degrees of freedom (DoF)... weather is one of the many elements that need millions of DoF and still cannot accurately predict it. mainly it's a vector analysis much akin to finite element analysis where each micro degree of freedom or say molecule of air is represented as one point interconnected in a web of points and each point's properties are altered relatively (similar principles how autonomous mini drones coordinate synchoronously) to each other.
many factors are considered: pressure, temperature and density of the air for sure. friction factors. drag factors. rotation of the earth. and that's the natural phenomena. include the heat given off the land, the radiation from the sun, airplanes, people, etc... its highly complicated. having done a weather station project, it's fair to say that there isn't a simple answer to your simple question. we measured wind direction, wind current, temp and humidity, visibility, pressure, etc... and we couls measure these things, but can't really say why say the wind went east or west... except tell you that its because of millions of degrees of freedom interacting with each other simultaneously and some things like weather are just like that.
